Specification of Letters Patent.

Patented Dec. 19, 1911.

Application led March 11, 1910. Serial No. 548,788.

To all whom it may concern:

Be it known that I, GEORGE F. WooDARD, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to improvements in baling presses.

The main objects of this invention are: First, to provide in a baling press an improved plunger actuating means. Second, to provide in a baling press an improved means for withdrawing the plunger. Third, to provide in a baling press an improved feed mechanism or device. Fourth, to provide in a baling press an improved driving connection. Fifth, to provide an improved portable baling press in which the operating power is derived from an engine, the engine being also adapted for use as traction power.

Further objects, and objects relating to structural details, will denitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The structure described constitutes one effective embodiment of my invention. Other embodiments wouldy be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an eective and ypreferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specication, in which Figure l is a side elevation of a structure embodying the features of my invention. Fig. 2 is an enlarged detail vertical section, taken on a line corresponding .to line 2-2 of Fig. l. Fig. 3 is a detail longitudinal section, taken on a line corresponding to line 3 3 of Fig. 2. Fig. 4 is a vertical section taken on a line corresponding to line 4-4 of Fig. 3. Fig. 5 is an enlarged detail vertical section, taken on a line corresponding to line 5`5 of Fig. 2 showing details of the plunger actuating mechanism and the driving connections therefor. Fig. 6 is a detail vertical section taken on a line corresponding to line 6-6 of Fig. 2 showing further details of this mechanism.` Fig. 7 is an enlarged detail section taken on a line corresponding to line 7-7 of Fig. 5. Fig. 8 is a perspective view of the clutch member 20. Fig. 9Vis a detail vertical section taken on a llne .corresponding to line 9-9 of Fig. 2, showing details of the feed device actuating mechanism. Fig. 10 is an enlarged detail showing the connections of the gear 38 to the shaft. Fig. 11 is a detail elevation showing a modied form of driving connection for the traction wheels. Fig. 12 is a sectional view showing a modified construction in which the links coacting with the plunger actuating lever are omitted.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the endsof the section lines, and similar reference numerals refer to similar parts throughout the several views.

Referring to the drawing, the frame, which is designated generally by the numeral 1, is preferably supported upon traction and carrying wheels 2.

At the forward end of the frame or body l is a platform 3 on which the engine 4 is mounted.

The baling chamber 5 and feed chamber 6 are of the usual or any desired construction.

The plunger 7 is mounted to reciprocate on the track 8. This plunger preferably consists of the head 9 and therearwardlyprojecting pieces l0, secured thereto and adapted to serve as a shoe or support for the head. A

The plunger actuating mechanism preferably consists of the lever 11, which is plvoted at l2 between the members 10 of the plunger. In front of the plunger is a transversely-arranged shaft 13, on which the eccentric 14 is revolubly mounted. This eccentric is connected to the upper end of the lever by means of the cable 15, the cable being adapted to be wound upon the eccentric, which is preferably provided with a peripheral groove for the cable,-see Fig. 2. The cable is connected to the eccentric at the point of its longest radii, so that the fastest movement is had on the starting movement, and the shortest where the greatest power is required at the end of the plunger stroke. The lever 11 is supported on the links 16. These links are preferably pivotally mounted on the shaft, as illustrated, and pivotally connected to the lever at 17. It is obvious that, when the plunger approaches the end of its stroke, this toggle is straightened out,

so that that is the point of the greatest power in the toggle. The eccentric is preferably actuated by providing a gear 18, which is secured to the shaft to revolve therewith, and connected to the eccentric throughwan automatically engaging and disengaging clutch connection. This, in the structure illustrated, consists of a laterallyprojecting clutch member 19 on the, eccentric and a coacting clutch member 2() on the gear. The clutch member 2O is arranged in a radially disposed slot 21, in the gear, to reciprocate therein, being held normally in its engaging posit-ion by means of the coiled spring 22, see` F ig. 7. This clutch member 20 isV provided with lateral projections 23, 24, 25 and 26, the projection 23 being adapted to engage the clutch member 19 on the eccentric, while the projection 24 is disposed to engage the cam trip 27, which is arranged soras to release 4the clutch at the end of the stroke of the plunger, the clutch member 20 being returned' to its engaging position by means of the spring 22. I preferably pro- 1 vide a bail-like member 74, which is Vpivoted on the side of the gear at 75, for holding the clutch member 20 in its inoperative position.

I preferably provide means for withdrawingthe plunger, consisting of the spring 28, which is connected to the plunger and to the hook 29 on the frame,-see Fig. 3,-and means for positively starting the plunger on its return movement, consisting of the slidably supported 4member 30, having an upwardly-projecting catch 31 thereon, which is engaged by the projection 2,6" on the clutch, after the clutches have been disengaged and thus positively starting the plunger on its return movement. The slide member 30 is drawn into engaging position by the actuation of the plunger, it being connected thereto by the chain 32. The member 30 is supported in a suitable slide way 33,-see Fig. 5. To assist in returning the parts to their initial position, I preferably provide a coiled spring 34, one end of which is connected to the plunger and the other to the plunger yactuating lever 11,-see F ig. 3.

To prevent the clogging of the mechanism in front of the plunger head, I provide a shield 85, which is pivoted to the plunger at 36, its rear edge being adapted to ride on the lever 11, as is illustrated in the drawing. As the plunger is advanced on its stroke, this shield collapses and passes into the feed chamber, preventing the introduction of the material into the feed chamber until the plunger returns to its initial position.

The driving connections for the gear 18 to the engine preferably consist of the shaft 37 on which. is a gear 38, arranged to mesh -with the gear 39. on the crank shaft 40 of the engine. The gear 38 is preferably yieldingly connected to the shaft 37 by means of.

standards or uprights 52.

the coiled spring 41, which is preferably adapted to serve as a clutch. The spring shown is a reversely coiled spring slidably supported in the slot 76 in the shaft, the ends 77 of the spring being adapted to engage the pins 7 8 on the gear. The cam lever 79 is pivoted at 80 in the slot 76 to engage the spring and force it inwardly against the tension of the spring 81, which acts on the plunger 82. (See Fig. 10.) This connection relieves the parts of shock on the starting of the engine and in the operation of the device.

On the shaft 37 is the gear 42 arranged in mesh with the gear 18. The shaft 37 is preferably connected to the traction wheels by providing the axle 44 with a sprocket wheel 45, and the shaft 43 with a sprocket wheel 46, the sprocket Wheels being connected by the sprocket chain 47. The shaft 48 is driven through the chain 83 and the sprocket wheels 84, and 86 on the shafts 37, 13 and 43 respectively. The sprocket wheels 84 and 85 are connected to their respective shafts by clutches 87 and 88. These clutches are actuated by the lever 89 which is pivoted on the bracket so that the clutches may be alternately engaged and thus reverse the drive tothe traction wheels. I preferably provide in this connection a feed deviceconsisting of the parallel bars 48 and 49, arranged in pairs. These bars are pivoted at 50 and 51, respectively, on the outer ends of these arms by means of the pivots 53 is a feed arm 54, and pivotally secured to the lower arm 49 is a coacting feed arm 55. The pivots are arranged to permit the movement of the bars to swing the feed arms down intoA the feed chamber with a tamping-like stroke. The arms 54 and 55 are preferably provided with a spring 56, which is adapted to hold them normally spaced,-that is, while it permits the yield ing of the bar 55, to enable the plunger to force the arms 54 and 55 upward in case they fail to rise by the regular means, thus avoiding breakage and accident, it holds this bar in a normally spaced relation to the bar 54.

The return spring 57 is connected to the pivot 50 and to the cross rod 58 carried by the bars 49. A cushioning or rebound spring 59 is preferably provided, one end of the spring being connected to the rod 58, and the other to the cross rod 60, carried by the bars 48. The spring 5 9 is preferably provided with a slotted connecting device 61.

The feed device is preferably actuated through the mechanism shown in Fig. 9, consisting of an actuated arm 62, pivotally mounted on the shaft 18, the arm being connected to the bar 48 by means of the cable 63 and the spring 64. An actuating arm 65 `is provided for the arm 62, the arm 65 being Secured to the secured to the shaft and being connected to the arm 62 through a clutch connection. This connect-ion shown is substantially the same as that illustrated in Figs. 7 and 8 for the eccentric 14 and the gear 18, and consists of the clutch member 20 on the arm 65 and the coacting clutch member 66 on the actuated arm 62. A trip 67 is provided for this clutch. The actuating arm 65 and the clutch trip are positioned so as to actuate the feed device and the plunger in proper sequence.

In the modication shown in Fig. 11, the shaft 37 is omitted, the driving connection for the gear to the shaft comprising a gear 68 secured or mounted directly upon the shaft 13. In this modification, the traction chain 4:7 does not pass around the sprocket wheel 46, but is held in driving engagement therewith by means of the idlers 69 and 70, as will clearly appear from the drawing.

Ihe steering gear, in the structure illustrated, consists of the steering post 71 on the lower end of which is a worm 72. This engages the worm 73 on the shaft 76, to

`which the chains 77 are connected. rIhe details of this will be readily understood.

In the modification shown in Fig. 12, the links 16 are omitted. The lever is here arranged to rest or travel upon the eccentric. The toggle effect is not, of course, here present.

I preferably provide the baling chamber with pairs of lugs 91 arranged on the side walls of the chamber and adapted to support the follower 91', as shown by dotted lines in Fig. 3. These lugs eectively support the follower, and, as is obvious, are a very simple expedient for the purpose. rlhe plunger is notched at 92 to permit it topass these lugs.

I have illustrated and described my improvements in detail in the form in which I have embodied them, although I am aware that various modifications in structural details are possible, but as these modifications will be readily understood by those skilled in the art to which this invention relates, I do not attempt to illustrate or describe them herein, but I desire to be understood as claiming my invention in the specific form illustrated as well as broadly within the scope of the appended claims.
